DETAILED DESCRIPTION

For a better understanding of the purpose of the present disclosure, thepresent disclosure is described below in further detail in conjunctionwith accompanying drawings and specific embodiments. It should beunderstood that the embodiments described below are merely to illustratethe present disclosure, rather than to limit the present disclosure.

Embodiment 1

As shown in FIG. 1, the embodiment of the present disclosure provides amethod for controlling an electronic cigarette, including the followingsteps:

S1: acquiring a work start signal of the electronic cigarette.

Whether there is a work start signal of the electronic cigarette can bedetected through a senor or a button switch. If the sensor senses a workstart signal or the button switch is triggered, it is indicated thatthere is a work starting signal. That is to say, the work start signalmay be generated by the sensor, also may be generated by a manualcontrol of the button. In case of manual generation, a button isarranged on the surface of the electronic cigarette, and when the buttonis pressed down, it is equivalent to give a signal to start smoking,that is, to generate a work starting signal. In case of automaticgeneration, a user sucks a mouthpiece on the electronic cigarette, suchthat the airflow pressure inside the electronic cigarette changes andthus a work start signal is generated. Then, a controller connected tothe sensor or the button switch can acquire the work starting signal.The controller can be a single-chip and the like. It is understandablethat the method of acquiring the work start signal of the electroniccigarette can also be performed by an acousto-optic element, and themethod is not specifically defined here. In the present embodiment, thecontroller of the electronic cigarette cyclically scans the airflowsensor of the electronic cigarette so as to acquire the work startsignal of the electronic cigarette.

S2: acquiring a time interval between starting work this time andstopping work last time.

The time interval between starting work this time and stopping work lasttime refers to a time interval between the current puff and the lastpuff, that is, the time difference between two puffs. The time of eachsmoking can be recorded locally or in the cloud. The method of acquiringa time interval between starting work this time and stopping work lasttime may include: acquiring according to a time interval betweenstarting sending a sensing signal this time and stopping sending asensing signal last time of an airflow sensor of the electroniccigarette, or acquiring according to a time interval between startingwork this time and stopping work last time of an electrical heatingelement of the electronic cigarette. For example, when a user smokes anelectronic cigarette, the airflow sensor of the electronic cigarettesenses a work start signal generated due to the user's smoking, then thecontroller acquires the work start signal through the airflow sensor andthus controls the heating element of the electronic cigarette to operateto vaporize the e-liquid to form an aerosol; after each puff, theelectrical heating element stops working, and the controller records thetime when the electrical heating element stops working. When the usersmokes again, the controller again controls the electrical heatingelement to work and records the time when the electrical heating elementstarts working.

That is to say, for two adjacent puffs, the time interval is the timedifference between the time when the electrical heating element stopsworking and the time when the electrical heating element starts working.It is understandable that, in one type of embodiments, when the workstart signal of the electronic cigarette is acquired through thetriggering of the button switch, for two adjacent puffs, the timeinterval is the time difference between the end time of the work startsignal and the start time of the work start signal. Therefore, themethod of acquiring a time interval between starting work this time andstopping work last time is not specifically defined here.

S3: comparing the time interval with a preset time interval, when thetime interval is greater than a first preset time interval, controllingthe electronic cigarette to work at a first power, and when a durationof the first power is greater than a first preset duration, turning offthe electronic cigarette; when the time interval is greater than asecond preset time interval but less than or equal to the first presettime interval, controlling the electronic cigarette to work at a secondpower, and when a duration of the second power is greater than a secondpreset duration, turning off the electronic cigarette; wherein, thefirst power is greater than the second power.

The first preset time interval is greater than the second preset timeinterval. The first preset time interval and the second preset timeinterval can be set according to requirements, for example, the firstpreset time interval can be set to 40 seconds, 50 seconds or 60 seconds,etc. The second first preset time interval can be set to 10 seconds, 15seconds or 20 seconds, etc. Of course, the second preset time intervalcan also be set to 0 second, which is not specifically defined here. Inone embodiment of the present disclosure, the first preset time intervalis not less than 60 seconds, and/or the second preset time interval isnot less than 15 seconds, which is more suitable for user's habits andthus can provide an appropriate amount of smoke for a user to inhale andachieve a good experience.

The first power and the second power can be set according to the typesof the electronic cigarette and the types of the e-liquid, which are notspecifically defined here. When the electronic cigarette starts work, avoltage of a battery supplying power to the electronic cigarette iscollected, then a duty ratio of a pulse width modulated signal iscalculated according to the voltage of the battery and the preset firstpower or second power, and then the conduction of a semiconductor switchwhich controls the operation of the electrical heating element iscontrolled according to the calculated pulse width modulated signal, soas to perform a heating control on the electrical heating element. It isunderstandable that the first power and the second power may be variableor constant. In one embodiment of the present disclosure, the firstpower and the second power are constant, for easy control.

Optionally, the first preset duration is less than the second presetduration. The first preset duration and the second preset duration canbe set according to requirements, for example, they can be set to 6seconds, 7 seconds, 8 seconds, 9 seconds or 10 seconds, etc. In thepresent embodiment, the first preset duration is 6 seconds, and thesecond preset duration is 9 seconds. If a duration of the first power isgreater than the first preset duration, turn off the electroniccigarette, that is, control the semiconductor switch which controls theoperation of the electrical heating element to be off. Similarly, if aduration of the second power is greater than the second preset duration,turn off the electronic cigarette. That is to say, the electroniccigarette is controlled to have a shorter duration of working at a highpower than at a low power, which better ensures the amount of smoke andavoids mouth burning due to long time of working.

Embodiment 2

Referring to FIG. 2, the present embodiment is similar to Embodiment 1in steps, except that: the S3 of the method for controlling theelectronic cigarette in the present embodiment further includes: whenthe time interval is less than or equal to the second preset timeinterval, controlling the electronic cigarette to work at a third power,and when a duration of the third power is greater than a third presetduration, turning off the electronic cigarette; wherein, the secondpower is greater than the third power.

The third power and the third preset duration can be set according torequirements, as long as the second power is greater than the thirdpower. Optionally, the second preset duration is less than the thirdpreset duration. The present embodiment sets multiple different powerscorresponding to multiple different time intervals in a process ofsmoking to atomize the e-liquid. The higher the power, the shorter theduration; the lower the power, the longer the duration. The presentembodiment better stabilizes the amount of smoke and avoids the problemof mouth burning due to high temperature.

Embodiment 3

Referring to FIG. 2, the present embodiment is similar to Embodiment 1in steps, except that: before acquiring a time interval between startingwork this time and stopping work last time, the present embodimentfurther includes the following steps.

S11: acquiring e-liquid remaining amount information.

Before a user uses the electronic cigarette, an e-liquid is filled inthe electronic cigarette and the total amount of the e-liquid is writtenin a memory of the electronic cigarette. During the work process of theelectronic cigarette, the consumption of the e-liquid is directlyproportional to the power; each time the user takes a puff, thecontroller of the electronic cigarette calculates the consumption of thee-liquid per puff according to the power and the time of each puff, andsubtracts the consumption per puff from the total amount before the puffafter finishing the puff, thereby calculating the current remainingamount of the e-liquid and writes it into the memory of the electroniccigarette. Therefore, after acquiring the work start signal, and beforeacquiring a time interval between starting work this time and stoppingwork last time, the controller acquires the current remaining amount ofthe e-liquid by reading the remaining amount of the e-liquid written inthe memory. It is understandable that the remaining amount of thee-liquid can be calculated by different methods according to differenttypes of e-liquids and different types of electronic cigarettes.Therefore, the method of acquiring the remaining amount of the e-liquidis not specifically defined here.

S12: comparing the e-liquid remaining amount with a preset e-liquidremaining amount, to judge whether the e-liquid remaining amount is lessthan a first preset remaining amount.

Calculate the difference between the e-liquid remaining amount read fromthe memory and the e-liquid remaining amount preset in the memory, toobtain the remaining amount of the e-liquid.

S13: when the e-liquid remaining amount is less than the first presetremaining amount, controlling the electronic cigarette to keep a turnoffstate.

That is to say, when there is a very little e-liquid, which is likely tocause dry burning immediately after smoking, the electronic cigarette isalso controlled to keep a turnoff state to avoid dry burning and protectuser's health, even if the work start signal is acquired.

In one embodiment of the present disclosure, when the e-liquid remainingamount is greater than or equal to the first preset remaining amount butless than a second preset remaining amount, control the electroniccigarette to work at a fourth power; wherein, the fourth power is lessthan the first power. That is to say, when the e-liquid remaining amountis greater than or equal to the first preset remaining amount but lessthan a second preset remaining amount, one cannot smoke at will. Byworking at a low power, the electronic cigarette prevents the electricalheating element from dry burning and can make full use of the remaininge-liquid and avoid waste. In a preferred embodiment of the presentdisclosure, the fourth power is less than the second power, to betterpreventing dry burning.

Embodiment 4

Referring to FIG. 1, the present embodiment is similar to Embodiment 1in steps, except that: before acquiring a time interval between startingwork this time and stopping work last time, the present embodimentfurther includes the following steps.

S14: acquiring environment temperature information.

Since different environment temperatures may lead to different surfacetemperatures of the electronic cigarette, the heat transferred to themouth of the user is different when smoking. A temperature sensor whichis connected to the controller may be arranged on the electroniccigarette. When the work start signal is acquired, the controller readsa temperature signal on the temperature sensor to acquire an environmenttemperature around the electronic cigarette, that is, the temperature ofthe user environment.

S15: adjusting the first preset time interval and the second preset timeinterval according to the environment temperature.

The controller adjusts the first preset time interval and the secondpreset time interval according to the environment temperature; thus, agood user experience can be obtained in areas at different temperatures.Optionally, the first preset time interval and the second preset timeinterval are directly proportional to the environment temperature, thefirst power and the second power are inversely proportional to theenvironment temperature. That is to say, the higher the environmenttemperature, the longer the first preset time interval and the secondpreset time interval, the lower the first power and the second power,which can better prevent mouth burning. The lower the environmenttemperature, the shorter the first preset time interval and the secondpreset time interval, the higher the first power and the second power,which can better ensure the amount of smoke and can provide sufficientheat to the user in cold environments.

The one or more modules are stored in the memory 2, which, when executedby the one or more processors 1, will execute the method for controllingthe electronic cigarette in any method embodiment above.

To sum up, in the method for controlling an electronic cigaretteprovided in the present disclosure, when the time interval is greaterthan a first preset time interval, the electronic cigarette iscontrolled to work at a first power; when the time interval is greaterthan a second preset time interval but less than or equal to the firstpreset time interval, the electronic cigarette is controlled to work ata second power; therefore, in the condition of cold start, a greatamount of smoke can be generated, thus the amount of smoke per puff isrelatively stable; if a duration of the first power is greater than afirst preset duration, the electronic cigarette is turned off, whichbetter avoids mouth burning due to long time of working. In addition, ifa duration of the second power is greater than a second preset duration,the electronic cigarette is turned off. The first preset duration isless than the second preset duration. That is to say, when the power islowered, a constant amount of smoke and a constant heat quantity areacquired by increasing the duration of inhalation per puff, so as tostabilize the amount of smoke and avoid mouth burning.
